6.4.2.1 Settings for Dynamic Cold Load Adjustments
In the list below, the setting ranges and default setting values for the pickup currents
are for an equipment with a nominal current rating I
N
= 5 A. For a nominal current rat-
ing I
N
= 1 A, divide the Setting Options values and Default Setting values by 5. Con-
sider the current transformer ratios when setting the equipment with primary values.
